Add Settings > Учебный каталог, off by default and available on ordinary writable profiles. Load ready example boxes, photos, TTKs and linked sample inventory additively; preserve own data, saved orders and edited examples when hiding or re-enabling. Respect company/profile scope, read-only permissions, failed downloads and tenant changes. Preserve the opened recipe guide across real catalog refreshes on iPhone. Integrated feature checks and full pull-request QA passed. Standard main QA and exact-asset production UI verification remain in place.
On phones place the existing menu editor above the catalog and add the same return-to-top control used by New Order. Preserve form nodes, unsaved values and active input focus; keep desktop/tablet layout and read-only permissions. Full QA passed, including iPhone WebKit and existing promotion focus regression. Extend real-asset production verification with a backend-blocked mobile-menu scenario.
Add compact accessible client summaries and menu discounts in percent or rubles with explicit durations. Preserve ordinary catalog prices and order line snapshots; derive current prices and expire promotions automatically without background writes. Keep fractional prices, legacy sale compatibility, and regression coverage. Full pull-request QA passed. Publication remains gated by full main QA and byte-for-byte production asset and UI verification.
